Acquisition of Qualia Elements from Corpora - Evaluation of a Symbolic Learning Method
Pierrette Bouillon, Vincent Claveau, Cécile Fabre, Pascale Sébillot · 2002
This paper presents and evaluates a system extracting from a corpus noun-verb pairs whose components are related by a special kind of link: the qualia roles as defined in the Generative Lexicon.This system is based on a symbolic learning method that automatically learns, from noun-verb pairs that are or are not related by a qualia link, rules characterizing positive examples from negative ones in terms of their surrounding part-of-speech or semantic contexts.The qualia noun-verb pair extraction is thus performed by applying the learnt rules on a part-of-speech or semantically tagged text.Stress is put on the quality of the learning when compared with traditional statistical or syntactical-based approaches.The linguistic relevance of the rules is also evaluated through a comparison with manually acquired qualia patterns.
